BPL at the medium voltage level

Local network stations have primary importance in the smart grid. They are the crucial communication interface between the network operator and the sensors and actuators, as well as the intelligent measuring systems in the low-voltage network. For integrating the distribution station into the energy data network, Powerline communication is useful at the medium voltage level. The data signal is transmitted using a PLC modem and signal coupler to the medium voltage line from a distribution station already accessible for communication (e.g. via fibre-optic cable). This is how the data reaches the distribution stations that were not previously accessible for communication. The advantage of a PLC medium voltage solution is that network stations can be integrated into the smart grid quickly, conveniently and cost-efficiently.
